2.0.1 - 2024-10-21

Added support for linear programming relaxations of causal scenarios, via InflationLP. This allows to run inflation hierarchies bounding the sets of classical and no-signaling correlations, per J. Causal Inference 7(2), 2019 (arXiv:1609.00672)
Added support for hybrid scenarios with sources of different nature, via the classical_sources argument to InflationProblem. Currently supported: classical-no-signaling (via InflationLP) and classical-quantum (via InflationSDP).
Added support for possibilistic-type feasibility problems (via supports_problem in InflationLP and InflationSDP).
Added initial support for structures with multiple layers of latent variables.
Improved support for structures with visible-to-visible connections, using the notation of do-conditionals.
Improved handling of certificates. This makes them easier to manipulate and evaluate.
Revamped the description of monomials. This makes the codes faster and consume less memory.
